ResumoParameters influencing the external doses to people living in areas with radioactive fallout, and methods for theoretical estimations of these doses, are discussed. The results from two different individual dose measurement projects after the Chernobyl accident are presented, one performed in the highly contaminated regions close to the power plant (Brjansk region of Russia), and the other in less contaminated areas far from the power plant (Oystre Slidre in Norway). In the former mean monthly effective doses of 200-250 µSv were measured, in the latter 66-95 µSv, both results including a natural background contribution of about 60 µSv. The results from the Norwegian programme correlate fairly well with published conversion factors between ground activity levels and effective dose equivalent values, while the observed results in the Brjansk region are lower than theoretical estimates.
